Osprey Falls Trail
What to Expect
Safety Advisory
This is serious grizzly bear country. The meadows along the service road and the canyon bottom are both high-activity areas. Carry bear spray accessible on your chest or hip, make noise consistently, and hike in a group if possible.
The canyon descent is steep, loose, and fully exposed to the sun. The climb back out gains 700 feet in less than a mile — allow twice as long for the return and carry more water than you think you need.
Trail Details
- 1
Start early from the Bunsen Peak trailhead near Mammoth — the three-mile road walk is exposed and heats up fast by mid-morning. You can also bike the service road section to cut the flat approach time in half, then lock up at the Osprey Falls junction.
- 2
Trekking poles are borderline essential for the canyon descent and especially the climb back out. The switchbacks are loose and steep enough that a slip on tired legs is a real possibility.
- 3
The base of the falls has a rocky alcove on the left side where spray catches the light perfectly in the late morning. Bring a lens cloth — the mist is relentless and will fog everything you own.
